Gitter aus Nanofallen und Verringerung der Linienbreite in einem Raman-aktiven Gas

(PresseBox) (Berlin, )
Die Verringerung der Emissionslinienbreite eines Moleküls ist eines der Hauptziele der Präzisionsspektroskopie. Ein Ansatz dafür basiert auf der Kühlung von Molekülen bis in die Nähe des absoluten Nullpunkts. Eine alternative Möglichkeit ist die Lokalisierung der Moleküle auf der Subwellenlängenskala. Ein neuartiger Ansatz in dieser Richtung wurde kürzlich von einem gemeinsamen Team des Max-Born-Instituts (A. Husakou) und des Xlim Instituts in Limoges vorgeschlagen. Dieser Ansatz verwendet zur Lokalisierung eine stehende Welle in einer gasgefüllten Hohlfaser. Sie erzeugt für Raman-aktive Moleküle ein Gitter aus tiefen Fallen auf Nanometer-Skala, was zu einer Verringerung der Linienbreite um den Faktor 10.000 führt.
